PER CURIAM:* Oscar Ramirez Pena appeals his guilty-plea conviction for possession with the intent to deliver over 900 pounds of cocaine.

No. 98-40563 - 2 - mitigating role in the offense; however, he provides no legal argument in support of his bare assertion of error. We have reviewed the record and the briefs of the parties and conclude that Pena’s argument concerning the Government’s alleged breach of the plea agreement does not amount to plain error. See United States v. Calverley, 37 F.3d 160, 162-63 (5th Cir. 1994)(en banc). Furthermore, the district court did not err in refusing to apply the safety-valve provision. See United States v. Wilson, 105 F.3d 219, 222 (5th Cir.), cert. denied, 118 S. Ct. 133 (1997). Pena’s argument concerning his mitigating role is deemed abandoned on appeal. See United States v. Tomblin, 46 F.3d 1369, 1376 n.1 (5th Cir. 1995). The judgment of the district court is AFFIRMED.
